SAW-JOINTER.

SPECIFICATION forming part of Letters Patent No. 738,354, datedSeptember 8, 1903.

Application filed ()ctoher 9,1902; SerialNo.126,543. (No model.)

clear, and exact description of the invention,

such as will enable others skilled in the art to which it appertains tomake and use thesame.

My invention relates to saw-.jointers; and it consists in a newconstruction thereof by which thejointer is cheapened and simplified,made more convenient for use, and the number of parts reduced. Itsessential features are a jointer-frame, integral lugs thereon to engagewith the file, a screw fitted to the frame, and a nut on the screw, saidnut and screw being adapted to engage with the file and retainit,respectively, in its two positions.

, 7 My invention is clearly shown in the drawings herewith, in whichFigures I and II are elevations showing the file retained, respectively,in flat and edge positions. Figs. III and IV are vertical and crosssections corresponding, respectively, to Figs. I and II.

In the figures, 1 indicates the jointer-frame provided with integralupper and middle flanges 3 and 4, perforated to receive the screw 6,integral lugs 7, and ribs 8, and with two integral bearing-lugs 9. Onthe screw is arranged the nut 11, fitted to recess 12 in the frame.

1 3 indicates the lower flange, in a cut-away central portion of whichis arranged theusual gage-plate.

The file is first arranged in the edge position to joint the teeth, inwhich it is retained between the tip of the screw and the two engagingor bearing lugs, as shown in Figs. II and IV. A slight bend may be givento the file when desired by the pressure of the screw, which is oftendesirable to follow the edge of the teeth. After the teeth have beenfiled and sharpened the file is set in the flat position on the ribs 8and there securely clamped between the nut and the lugs 7 and is used toremove any feather-edge or bur left in filing and toeven the setperfectly.

with the nut when the screw-tip is forcedv against the file.

2. In a saw-jointer, the combination with the frame having twointegral,parallel flanges, correspondingly perforated, of the screwarranged in said perforations, and an angular nut fitted to the screwand having one of its sides adjacent to the frame so that it will notrotate when the screw is turned.

3. In a saw-jointer, the combination with the frame having'an integralcentral flange, an integral, upper flange parallel to the central flangeand on one side thereof, an integral bearing surface or surfaces on theother side of the central flange and a recess in the frame between theflanges and adjacent to the central flange, of a screw arranged incorresponding perforations in the flanges and having its tip projectingtoward the bearing surface or surfaces, and a nut fitted to the screwand having a portion arranged in the recess.

4. In a saw-jointer, the combination with the jointer-frame havingparallel, integral, upper and middle flanges, a substantially square,central recess between the flanges and adjacent to the middle flange,and two lugs arranged parallel to and below the middle flange, of ascrew arranged in central perforations in the t-wo'flanges, and a nutfitted to the screw and having one side arranged in the recess.

In testimony whereof I affix my signature in presence of two witnesses.
